Thank you so much for these videos. They cover everything that no one else has been able to organize and explain in a suitable manner. Keep teaching your great.
Wow! I am a retired master tech/ shop owner and this is one of the best training videos I've ever seen. The animation added to the video content is amazing. Thanks for taking the time to publish such an amazing educational video. I've been doing this for 21 years and wish i had something like this when i started in automotive AC systems.
Professor thankful for your efforts to teaching the easiest way to learn the a c system appreciate 👌👍🙏💐💐💐💐💐
Wow, very well done! Thank you
Very good explanation. Thanks for publishing this.
you are an angel. thank u for sharing your knowledge
These videos are very helpful, thanks for sharing.
Awesome video thanks for making it
Gracias
Where can I get this file or program, this would make teaching my students so much easier in addition to me drawing on the board and the consolabs we have. Great stuff!
Hi Jason, Sorry but I can not share this file. I have used this video by playing it while turning the sound off during a mobile class in which I had a computer failure. It worked fairly good and I was able to stop and start the video as needed. I also made this video so I would have this animation forever. I had some great animations on flash and lost all of them when flash no longer worked. Good luck, PP
@@ProfessorPentane no worries, I’m a new instructor coming from the dealership after 20 years or so. Teaching yourself is one thing but teaching young minds is totally different and foreign. Thanks anyways
Does the capillary tube read temperature or pressure? At time 17:45 you said psi. The relationship between temperature and pressure would depend on the charge level and other factors?
You are correct, the capillary tube senses temperature that changes the pressure in the tube causing the TXV to move. Sometimes I get so into my presentation-, my speaking is getting ahead of the thinking. Sorry for any confusion. PP
@@ProfessorPentane it’s all making sense after watching your AC theory videos. I forgot that saturation temperature is close to pressure with automotive refrigerants. Thanks so much Prof Norman.
In residential system we use thermocouple on both suction and discharge line and measure the values to derive eventually super heat. Is there a reason why that method is not used.
strength and volume maybe,
residencial AC are always 4x or more bigher than what the car have
Good day sir what would be a problem if the senario is 50-60 psi suction side and the discharge line is normal 175 -200psi at the first start of the compressor the temp is ok(40-45 psi suction)then after few minutes the engine is running the suction side will read 50-60 psi still the discharge is normal.thank you hope you can answer my query.
perhaps the idle is too low and the condenser is too hot,
on idle it should'nt reach 200,
it should reach that if reved up. to 2k rpm or more
